Hyped as the "Ultimate GEforce", the 1080 Ti is NVIDIA's latest flagship 4K VR ready GPU. It supersedes last years GTX 1080, offering a 30% increase in performance for a 40% premium (founders edition 1080 Tis will be priced at $699, pushing down the price of the 1080 to $499). It also supersedes the prohibitively expensive Titan X Pascal, pushing it off poll position in performance rankings. The 1080 Ti is based on the Pascal architecture and features a slightly modified version of the same flagship GP102 silicon found in the Titan X Pascal. It has 11GB of the high bandwidth GDDR5X video memory (versus 12GB in the Titan X Pascal) and an impressive 11GB frame buffer. Like the Titan X Pascal, it features 12bn transistors and 3584 CUDA cores which can run at a boost clock speed of 1.582 GHz – 3% faster than the Titan X Pascal's 1.531 GHz. This increased speed is partially attributable to the 1080 Ti’s new dualFET power system which allows the chip to run at higher power and more efficiently than ever before. The release of the 1080 Ti comes ahead of the competition from AMD's Vega - rumored for release in Q2 2017. Vega is AMD's next generation graphics card (following on from Polaris 10) featuring their new HBM2 die which is alleged to have eight times the capacity of GDDR5 with half of the footprint. NVDIA's own next generation graphics cards (Volta) are in the pipeline for 2018. [Mar '17GPUPro]

The new AMD R9 390 is the direct successor to the R9 290. Both cards share the same GPU but the R9 390 is factory overclocked. The R9 390 has a 5% higher stock GPU clock, and a substantial stock memory clock increase of 20%. Additionally the R9 390 sports a minimum of 8GB of VRAM versus 4GB on the R9 290. At the current price levels of $329, the R9 390 can't compete given that R9 290s can be had for around $260. The increased VRAM will rarely help even at ultra high resolutions and in any case, most 4K gamers are likely to seek more GPU power than the R9 390 has to offer. We have seen several samples of the R9 390 and they scored an effective speed of 88.5% which, as expected, matches the speeds seen on overclocked R9 290s. On the face of it purchasing an R9 290 at a discount and then manually overclocking will result in the same performance as an R9 390 but with a saving of around $70. [Jun '15GPUPro]
